Microinverter Sizing Guidelines


                        DC/AC Ratio = Panel Wp / Micro AC Output

                        Voc cold = Voc x 1.14 (check < max Vdc)

                        Isc check: Panel Isc < Micro max Idc

DC/AC Ratio Effects

Ratio	Clipping	Benefit
1.0	None	No clipping loss
1.1	~0.5%	Better low-light
1.15	~1%	Optimal balance
1.2	~2%	Cost savings
1.33	~4%	Max DC input
